Y., a corporation of NewJersey Application August 14, 1930. Serial No. 475,158 6 Claims. (01.229-511) This invention relates in general to fibre containers for thepackaging, transporting and dispensing of a variety of products and moreparticularly to a fibre container having a permacent bottom and animproved easily removable .netal cap.

The primary purpose of this invention is the provision of a novel,simple, inexpensive, tight fitting metal closure for a fibre container,which combines all the advantages of a simple slip cover with theadditional merit of having a better locking engagement with cooperativeparts of the container body than the ordinary type of slip cover.

An important object of this invention is the provision of such amodified slip cover having a locking channel or groove in its dependingflange which cooperates with looking projections upon the fibre bodywhich can be added to the con- 0 Ientional stock type of fibre bodywithout any substantial structural changes in the latter.

Numerous other objects of the invention will be apparent as it is betterunderstood from the following description, which, taken in connectionwith the accompanying drawing, discloses a preferred embodiment thereof.

Referring to the drawing:

Fig. 1 is a perspective view of a fibre container and closure embodyingthe invention, showing the metal cap removed and in superposed alignmentwith the container body;

Fig. 2 is a fragmentary elevational view of the container body andclosure fully assembled;

Fig. 3 is a horizontal cross sectional view of the container body takenalong the line 33 of Fig. l; and

Fig. 4 is an enlarged, fragmentary, vertical cross sectional view of theupper part of the container body and closure showing the cooperatinglocking elements.

To illustrate a preferred embodiment of the invention, I have shown onthe drawing a container having a cylindrical body 11, of fibre or othersuitable relatively soft material, and having abottom end 12, preferablyof metal, crimped or otherwise permanently secured to the body 11. Thebody 11 has a smooth exterior annular wall surface and terminates at thetop into a straight annular edge 13.

Where the body is composed of a plurality of layers of material, asshown in Fig. 4, the looking projections, having shanks passing throughsaid layers, aid also in securing said layers together to preserve thesolidity of the body.

A short distance below the top edge 13 and in a parallel annular linetherewith, I-have provided a series of metallic locking projections orbeads, spaced an equal distance from each other. In the preferredillustration on the drawing, three of these locking beads are shown.However, more than three may be employed.

Each of these locking projections comprises a well known type of splitmetal rivet, having a rounded rivet head or bead 14 and integraltherewith a rivet pin 15 which is split into two pointed shanks 16 and17, which are adapted to pierce or perforate the relatively softmaterial of the wall of the fibre body 11 at the desired point oflocation of the locking projection and which, after the perforation hasbeen accomplished, may be radially separated or parted and bent backupon themselves in opposite directions to secure 1y rivet the lockingbead in position upon the body wall.

A metal cap or cover 18 is adapted to fit snugly over the upper outersurface of the container body 11. It is of the general configuration ofa slip cover and comprises a substantially flat central panel 19, aslanting annular portion 20, a flat, horizontal annular shoulder portion21 adapted to overlie and engage the annular top edge 13 of the body 11,and a vertically depending flange of substantial width.

This depending flange, instead of having a straight flat annular wall asin the simple type of slip cover, has an upper straight vertical portion22, a lower straight vertical portion 23, and has its lowermost edgeturned outwardly, upwardly and inwardly to form a hollow bead or curl24. The straight annular portions 22 and 23 of the depending flange areon a plane which is at right angles to the plane of the shoulder 21, andthe metal between these two straight portions is bent outwardly to forma V-shaped annular groove, comprising an upper V-shank or leg 25, alower V-shank or leg 26 and an annular apex 27.

In applying the cover 18, the curled edged the depending flange of thecover will easily slip over the top edge 13 of the body 11, until thecover meets the rivet heads 14. The latter will then slightly oppose adownward pressure upon the cover 18, and being rounded, they will yieldinwardly to this downward pressure and owing to a slight resiliencyinherent in the cylindrical fibre body 11, these rivet heads 14 will bepressed inwardly by the straight portion 23 of the depending flangeuntil further downward pressure upon the cover 18 brings the rivet heads14 into alignment with the annular groove of the depending flange, whenthey will snap back into normal position and become locked with thegroove or channel of the depending flange.

A substantially secure locking engagement is accordingly establishedbetween the body and cover which will positively resist accidentaldisplacement of the cover and yet will permit easy manual removal of it.

It will be quite apparent that this invention is equally adaptable tocontainers of other than cylindrical shape and it is also conceivablethat a fibre cover with looking groove might be substituted for themetal cover preferably illustrated in the drawing.

It is thought that the invention and many of its attendant advantageswill be understood from the foregoing description, and it will beapparent that various changes may be made in the form, construction andarrangement of the parts without departing from the spirit and scope ofthe invention or sacrificing all of its material advantages, the formhereinbefore described being merely a preferred embodiment thereof.

I claim:-

I. In a fibre container, in combination, a fibre body having metalrivets arranged annularly adjacent its top edge and having shankspassing through said body, a cap arrangeableover said body and having adepending flange provided with a recess on its inner surface and adaptedto snap over the heads of said rivets to provide a removable lockingengagement between said body and said cap.

2. In a fibre container, in combination, a fibre body having metal beadsarranged peripherally adjacent its top edge and having shanks passingthrough said body, a slip cover arrangeable over said body and having aninternal recess adapted to snap over the heads of said beads to providea removable locking engagement between said body and said cover.

3. A closure for a fibre container, comprising in combination, a fibrebody, metal locking beads upon said body and having shanks passingthrough said body, a cap of the slip cover type, said cap having agroove cooperating with the heads of said beads to provide a lockingengagement between said body and said cap.

4. A closure for a fibre container, comprising in combination, a fibrebody, metal locking beads separate from and secured peripherally to saidbody adjacent its top edge and parallel therewith and having shankspassing through said body, a cap of the slip cover type, said cap havingmeans cooperating with the heads of said beads to provide releasableinterlocking engagement between said body and said cap.

5. A closure for a fibre container, comprising in combination, a fibrebody, a series of spaced metal locking beads separate from and securedperipherally to said body adjacent its top edge and having shankspassing through said body, a cap of the slip cover type, said cap havinga depending flange with a locking groove adapted to releasably interlockwith the heads of said beads.

6. A closure for a fibre container, comprising in combination, a fibrebody, a series of spaced metal locking beads separate from and rivetedperipherally to said body in a line parallel with its top edge, a metalcap of the slip cover type, having a depending flange with an internalV- shaped channel, adapted to snap over the heads of said beads and forma releasable locking engagement therewith.
